No, it's atties not screwing onto the top cap. See the list below.
Yeah, so...I got the same advice and did that. I'm sure it was just a tap near the end of its life, and that's why I'm not fussed. More will fit on it now, but it's taken some serious work. I nicked a chunk out of my palm doing that push/pull thing with a cartomizer. I was honestly worried that I was going to flat-out break the top cap, but what happens is that my DID screws in now. It's rough, even after cleaning the threads with contact cleaner, but it screws on.
I'll just go buy a nice tap at some point. Seems like it's not a bad thing to have now that I've had 510 issues.
What of this counts as crap quality:
3 Fatty v2s
An entire box of Boge cartomizers.
An hh.357.
An avid vaper 510 to 901 adatper.
2 Tridents
A DID (yes, the MMV one, not a clone)
2 Atmistique Divers
If you'll go back to my first question, you'll find that I
knew cheap atties could be at fault and that I was waiting to contact MMV until I treid something more on the Poldiac's level.
That's the list of stuff that wouldn't fit on my Poldiac until I started really man-handling it to condition the threads as you guys suggested. Now, the DID fits, most of the cartos, and one of the Divers. The rest still don't, but it's fine. I've been using it with a Fatty v2, but I bought it in person...and we had to try 4 of them to get one that fit. Also, all of it fits on my Silver Bullet, my Provari, and my Gus. None of them are as "nice" as the Poldiac, but their 510 connections fit more stuff. I get that tight tolerances are a thing and that's probably part of why the Poldiac seems to hit better. But, it doesn't matter how well it hits if nothing will screw onto it.
If I hadn't asked for advice, I would have returned or sold the Poldiac on day 1. I think I came out on top, since at least I can use it now.
You and I have very different definitions of the word Quality.
Why are you being such an

? I have
never said that the Poldiac is a bad device or that MMV is a bad company or that Jim is a bad guy.
I've said that something was wrong with my top cap and that I was slightly disappointed with the customer support I got from clicking "contact me" on their website. And that was only because of what people ITT said MMV would probably do.
It's a good thing you're a fanboy of a device people generally respect. You wouldn't last 5 posts in a Provari thread if you're getting defensive because some guy
wants the mod to be awesome and doesn't feel like paying $30 in shipping to maybe get a replacement for a $30 part.
IDK...maybe it was the "not buying a second
as quickly" comment you misunderstood. The old list (if they'd just offered to mail me a top cap) was 2nd Poldiac, 2nd Reo, Nemesis, list for a vela. Now, it's 2nd Reo, Nemesis, list for a vela, 2nd Poldiac.
I don't see how you can take that as an insult.
